Localized Routing for Proxy Mobile IPv6
Abstract
Proxy Mobile IPv6 (PMIPv6) is a network based mobility management
protocol that enables IP mobility for a host without requiring its
participation in any mobility-related signaling. PMIPv6 requires all
communications to go through the local mobility anchor. As this can
be suboptimal, Localized Routing (LR) allows Mobile Nodes (MNs)
attached to the same or different Mobile Access Gateways (MAGs) to
route traffic by using localized forwarding or a direct tunnel
between the gateways. This document proposes initiation,
utilization, and termination mechanisms for localized routing between
mobile access gateways within a proxy mobile IPv6 domain. It defines
two new signaling messages, Localized Routing Initiation (LRI) and
Local Routing Acknowledgment (LRA), that are used to realize this
mechanism.
